使用哈希集删除重复的字符。
这是字符串-
string myStr = "kkllmmnnoo";
现在,使用HashSet将字符串映射到char。这将从字符串中删除重复的字符。
var unique = new HashSet<char>(myStr);
让我们看完整的例子-
using System; using System.Linq; using System.Collections.Generic; namespace Demo { class Program { static void Main(string[] args) { string myStr = "kkllmmnnoo"; Console.WriteLine("Initial String: "+myStr); var unique = new HashSet<char>(myStr); Console.Write("New String after removing duplicates: "); foreach (char c in unique) Console.Write(c); } } }
输出结果
Initial String: kkllmmnnoo New String after removing duplicates: klmno
